This is the Polaris PCX iQ. A corded robotic pool cleaner designed for pools up to 50ft with a filter basket and smartphone app. And it looks a lot like the Polaris Freedom, the cordless version. And today, I’m going to dive in and let you know if it is worth it or not.
Hey guys, I’m Ryan with Actually Used, where we put products to the test. With actual data and testing with my manometer, I’ll show you the real world suciton power to see how it stacks up. And while the PCX didn’t disappoint, it is lower than some of the competition. So let’s dive into all the features and see if the Polaris PCX iQ is worth it for you.
Filtration: Big Bin, Basic Mesh
The first thing you notice when you pop the hood is the filter canister. It’s rather large—Polaris lists it at roughly five litres, and I believe it. Leaves, grass, and even bugs… it swallows them all and still has room to breathe. The lid is clear, so you can see the junk piling up before you bother yanking the robot out. A single latch releases the basket; shake it out, hose it off, click it back in. Easy.
Think of NanoFilters as the pool-robot equivalent of swapping a screen door for a HEPA cartridge. Polaris’s basket stops debris you can see; Dolphin’s pleated NanoFilters snag what you can’t. They’re folded like an accordion, so the surface area is massive—big enough to trap particles down to about 2 microns, which is finer than most sand filters on your pool equipment pad.
During head-to-head testing, a Premier running NanoFilters pulled out what looked like light-gray silt the PCX had left suspended; the difference was obvious by mid-afternoon, with the Premier pool showing that “crystal clear” sparkle while the PCX water still had a faint cloudiness. Owners who battle post-windstorm cloudiness, desert dust, or the yellow sheen of spring pollen swear NanoFilters are the single upgrade that finally lets them skip the clarifier tablets.
There’s another benefit you don’t read about on the box. Because NanoFilters keep water inside the canister flowing through a dense pleat pack, the robot acts like a moving micro-filter on top of your main pump. NanoFilters effectively turn your robot into a second pool filter.
That means every two-hour cleaning pass quietly polishes a chunk of the pool’s volume—so the water that returns to the grid skimmer already has less gunk in it, easing the load on your sand or cartridge filter.
With the PCX’s mesh basket, you’re not getting that bonus; the big stuff is gone, but fine debris keeps doing laps until the pump catches it. If you’re the kind of owner who notices wants sparkling clean water at all times, these pleated NanoFilters in a Dolphin robot are a must-have. So keep that in mind before pulling the trigger on the Polaris PCX iQ.
App Control: It Actually Works
Polaris didn’t cripple the software on this middle model. You still get full iAquaLink integration: start or stop a cycle, pick a mode, see the timer counting down, drive the robot like a remote-control submarine, even trigger the lift-to-surface trick—all from your phone. Setup is easy: power up the control box, connect to the cleaner’s hotspot, hand it your Wi-Fi password, and you’re done. The entire process took me about a minute.
Once connected, the robot stays connected. Because it’s corded, robot is connected the whole time it’s underwater, so your phone never loses track of the bot mid-cycle. Cordless cleaners can’t say the same; they disappear from the network the moment they hit the water, which makes “smart control” kind of moot.
Cleaning Modes: Two Buttons, That’s It
If you’ve watched my Polaris VRX iQ review, remember how the VRX boasts seven different cycles? The PCX 868 trims that list down to just two: Floor Only and Floor plus Walls and Waterline. That’s it, no deep-clean, no spot-clean, no water-line-only. On paper it sounds limiting. In practice it covers almost everything a normal owner needs.
Tap Floor-Only after a light wind. Tap the full-coverage mode when you want a proper scrub. Runtime adjusts automatically—about an hour-twenty for the floor pass on my pool, roughly two hours and change for the full job. The pattern is random, but by the end of the run it reaches every corner. Would I love a dedicated water-line cycle? Sure. But two modes are simpler to pick, harder to screw up, and less likely to confuse a house-sitter when you’re on vacation.
Corded Versus Cordless
Everybody loves the idea of a cordless cleaner until reality shows up. Batteries die after ninety minutes, charging takes half a work-day, Wi-Fi disappears underwater, and you cross your fingers that your house doesn’t catch on fire like it has with some popular cordless brands.
Meanwhile, the boring old cord in the PCX just works. 60ft of double-insulated cable gives it range for pools up to fifty feet long, and the swivel joint Polaris uses actually prevents knots and kinks. I stretched the cable out across hot concrete several times; no memory coil, no twist.
If you’re the set-it-and-forget-it type, corded is still king. You plug it in, schedule it, and ignore it. The cleaner doesn’t come up gasping for a charge, and your phone doesn’t lose the connection halfway through a cycle.
Weekly Timer: True Autopilot
Inside the iAquaLink app there’s a little calendar icon. Pick Monday, Wednesday, Friday, pick which of the two modes you want, hit save, and walk away. The robot will wake itself up at that time on those days, clean the pool, climb the wall, and wait politely at the surface for you to haul it out.
I ran that schedule for the entire month. No recharging, no hauling the robot out of the water daily. It’s super easy and I highly recommend a robot with a weekly timer.
Lift System: Easy to get out
Polaris calls it the Easy-Lift Removal System. You hit a button—on the control box or in the app—and the robot finds the nearest wall, climbs until its nose breaks the surface, then fires a jet of water out the back to drain itself. What you pull out is maybe two-thirds the weight of the soaked cleaner. No more fishing the robot out with a pool pole like a cordless bot, just an easy to lift out robot.
Suction and Scrubbing: Middle-of-the-Pack Muscle
Polaris doesn’t publish a PSI spec, so I dragged out the trusty manometer, hooked it up, and recorded the resilts. The Polaris PCX 868 pulled an average of 1.5 PSI at the intake port. For context, the Dolphin Quantum sits around 1.4, the Sigma closer to 2.0, and a Premier around 2.2.
Translation: It’s about average. It’s not the ProLine performance you get with the Sigma and Premier’s commercial grade. And to me, this is what matters most. So for that reason, I’d suggest looking into those cleaners. But if you are wanting a Polaris, it’s not a bad option – it’s just not the best.
Price and Value
The Polcaris PCX iQ 868 hovers around thirteen hundred dollars as of today. At that price range, it’s a compelling package: Wi-Fi, lift system, filter basket, decent suction, proven brand. At the high end you’re edging into Dolphin Sigma territory, and that bot gives you better filtration, stronger suction, and gyroscope navigation. Is the Sigma worth $200-300 more? Yes – by far.
Real-World Alternatives in Plain English
- Dolphin Sigma – Costs a bit more than the Polaris PCX, but you get triple motors, 2.0 PSI suction, a gyroscope that straightens its driving path, and replaceable NanoFilters that polish water crystal clear.
- Dolphin Premier – The leaf-eating machine. Strongest suction of the bunch at 2.2 PSI, plus interchangeable media. Plus, it’s even cheaper than the Sigma - you’ll give up the app, but it’s not something you need if you’ve watched my review.
- Dolphin Quantum – Think of this one as the budget smart pick. It packs a giant larger XXL MaxBin and NanoFilters. Navigation gets an upgrade, too: SmartNav 2.0 maps the pool so it stops double-tracking the same lanes. No Wi-Fi, but at that price you’re paying for reliable cleaning, not phone control. And it also has a Weekly Timer with it. Great choice if you want big-basket convenience and decent polishing power without stretching the wallet.
And for my cordless crowd, just don’t. If you’ve watched any of my videos, you know they just don’t perform. I’ve used the Polaris Freedom, all the top Aipers, Beatbots, and the Dolphin Liberty – literally all of the top cordless cleaners. And I just can’t recommend any. You want a cleaner with a Weekly Timer, good suction power, and NanoFilters. And you just cannot get that in a cordless cleaner.
Final Thoughts
So what is my final thoughts on the Polaris PCX iQ and should you buy it?
It’s a solid robot, no question. But, it simply isn’t as powerful as other robots I’ve tested.
The Polaris PCX 868 iQ gives you a nice debris basket, rock-steady Wi-Fi control, a true weekly timer you can “set and forget,” and that corded setup means zero battery drama. But if you’re chasing top-tier water clarity and powerful suction, the Dolphin Sigma and Premier still outrun it—mainly because their pleated NanoFilters pull the ultra-fine dust this mesh basket lets slide. So: rock-solid robot, great for everyday debris, just know the ProLine Dolphins do the deep-clean flex a notch better.
And that’s really the summary here. It’s solid, but better options are available.
Given the choice, would I pick the Polaris PCX iQ over a Dolphin Sigma, Dolphin Premier, or Dolphin Quantum? No – I don’t think so.
And that’s all for today – thanks for watching and I’ll catch you on the next one!
